用各向异性磁阻传感器探测核磁共振
Detection of nuclear magnetic resonance with an anisotropic magnetoresistive sensor
摘要：
我们报告检测核磁共振（NMR）使用各向异性磁阻（AMR）传感器。使用了"远程检测“装置，其中流动水中的质子在超导NMR磁体的场中被预极化，被磁反转，随后用位于磁体和绝热逆变器下游的AMR传感器检测。AMR传感非常适合微流体“芯片实验室”应用中的NMR检测。
英文摘要：
We report detection of nuclear magnetic resonance (NMR) using an anisotropic magnetoresistive (AMR) sensor. A ``remote-detection'' arrangement was used, in which protons in flowing water were pre-polarized in the field of a superconducting NMR magnet, adiabatically inverted, and subsequently detected with an AMR sensor situated downstream from the magnet and the adiabatic inverter. AMR sensing is well suited for NMR detection in microfluidic ``lab-on-a-chip'' applications.
